IV. D. IVILLIAMS, OF RALEIGH. NORTH CAROLINA.

WAGON-BRAKE.

Specification of Letters Patent No.

To all whom it may concern:

Be it known that I, IN. D. VILLIAMS, of Raleigh, in the county of akeand State of North Carolina, have invented certain new and usefulImprovements in agom' Brakes; and I do hereby declare that the followingis a full, clear, and exact description of the same, reference being hadto the accompanying drawings, forming part of this specification, inwhich Figure 1, is a plan of the same as it appears when the brake isnot in operation. Fig. 2, is a longitudinal section of the same throughthe line w, m, in Fig. 1.

Similar letters of reference in each of the several figures indicatecorresponding parts.

A, A, represent the axles which are united together and braced in theordinary manner and have the wheels B, B, B, B, secured on their outerends.

C, C, are iron clamps placed around the front axle A, in the mannershown, in Fig. 2; these clamps have projecting ears or eye pieces a, a,cast on their front side, to which the swinging links Z), 6, areconnected by means of the pins (3, which pass horizontally through themand the eyes of the pieces a, a, and form swinging or rolling joints. Onthese pins the links 7), are allowed to turn freely. These links 6, b,serve to connect the the front hounds D, D, of the wagon to the axle orthe clamps O, C, of the same, the pins (Z, (Z, passing through the frontends of the links and through the back ends of the hounds in the mannershown in F 1, and 2, thereby forming another hinged or rolling joint.Thus it will be seen that double swinging or rolling joints are formedbetween the front hounds D, D, and the front axle A, the object of whichwill be stated shortly. The hounds D, D, are fastened tightly to thesides of the reach E. and to the cross piece F; in which the back end ofthe reach E, is secured. On top this reach. a short distance from thefront axle, is placed a stout cross piece G, which extends nearly thewhole width of the wagon and is secured at its center to the reach by abolt as shown in Fig. 1, and braced near each end by the rods or bars 6,e, which connect it with the crosspiece F, as shown in Fig. 1. On eachend of the cross piece G, is a metal bearing f, f, to which theprojecting arms or pieces 9, g, of the bar I which carries the brakes h,h, are secured and allowed to turn freely these hearings being thecenter upon 10,218, dated November 8, 1853.

which the brake turns as it is thrown from the back to the front of thereach E, when it is desired to dump the load.

By making or forming double swinging or rolling joints H, H, between thefront axle and hounds as seen in Figs. 1, and 2, I am enabled to renderthe brake perfectly self acting with the aid of the horse, drawing thewagon, for it will be seen by examining Figs. 1, 2, (in black lines),that if the horse is traveling on a level surface the brakes will bealways disengaged from the wheels at which time as is well known it isnot required or desired that they should operate, but that if the horseshould be traveling down an incline plane and the wagon consequentlycaused to have a greater momentum than the speed of the horse the brakeswill be instantaneously applied to the wheels, or are made to assume theposition shown in red lines in Fig. 2, thereby preventing too great andsudden weight coming on to the horse, also avoiding the seriousconsequences arising from the use of a greater proportion of the brakesnow in common use and likewise saving the time and trouble of applyingor disengaging the brakes by hand, for as soon as the horse reaches thelevel surface he instantaneously draws the brakes off the wheels again.

In Fig. 2 of the drawing will be seen the manner in which the brake isthrown to the front of the reach E, when it is desired to back thehorse; the dotted lines in said fig ure indicating its position whenthus thrown back. This is necessary in case it is desired to dump theload, and therefore it is important. In other brakes this di'fliculty ismost generally experienced. This simple contrivance very effectuallyobviates any such difliculty of not being able to back the wagon, and isvery easily operated, it swinging on a center or bearings, and can bethrown back and forth with great ease and despatch.

I do not claim a double crank attached to the front hounds of the wagonand connected to the brakes behind the wheels for applying the powerthrough the action of the horse, forward and backward; but

hat I do claim as my invention and desire to secure by Letters Patent,is

1. Forming two swinging or rollingjoints between the front axle A, andthe front hounds D, D, in combination with the swinging brake I, h. h,g, g, arranged on top the of swinging on a center so that it may be1ethrown over toward the front of the reach When it is desired to dumpthe load, and

again thrown to its proper place after dumping as herein fully setforth.
